Abstract. In general, it is difficult to visualize 4-D mathematical data with interdependence among variables in 3-D space that we are able to perceive. In our previous work, we developed an embodied 4-D space display system for observing various 4-D objects; the system can intuitively overview and understand the shapes of 4-D objects from various 4-D positions and directions in 4-D space. The system enables us to create any 4-D mathematical data without omitting any properties. Using the system, we can obtain various mapping structures of 4-D mathematical data such as complex functions and functions with three variables, and easily discover characteristics such as the singular point of the complex function and the extremal value of the 3-D scalar function. It is expected that our approach will be useful for the development of perception of 4-D mathematical data.
